6.11-stable review patch. If anyone has any objections, please let me know. ------------------ From: Masahiro Yamada <masahiroy@xxxxxxxxxx> [ Upstream commit 340fd66c856651d8c1d29f392dd26ad674d2db0e ] Commit be2881824ae9 ("arm64/build: Assert for unwanted sections") introduced an assertion to ensure that the .data.rel.ro section does not exist. However, this check does not work when CONFIG_LTO_CLANG is enabled, because .data.rel.ro matches the .data.[0-9a-zA-Z_]* pattern in the DATA_MAIN macro. Move the ASSERT() above the RW_DATA() line.
